N. PETERS. Mmn n lw. wmln am m a To all whom it may concern: Be it known that I,.1)AN1EL, GUPTAI'L, of

Elgin, in theeouuty of" Kane and State of'l lli nois, have invented a new and Improved Bali "UN TED ATEs PATENT "OF ICE.

DANIEL GUPTAIL, or ELGiN,'1LLINOIS.

. Specification forming part of Letters Patent No. 2. 54l, .dated June 2 6, 18130.

in g Attachmentfor Harvesters andfIdo hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- V Figure 1 is a ertical section of the platforin and frame of a harvester, taken in the line was, Fig. 2 Fig. 2, a plan or top iew of thesame. Similar letters of reference indicate corre- 'sponding parts in the twofigures.

This invention consists in-an arrangement ,of a system of levers known as the lazy-.- "tongs with rakes and a peculiar operating mechanism, substantially as hereinat'ter described, whereby a very simple and eflicient raking de'viceis obtained, and onethat may be applied to all harvesters that'haye'their sickles behind-the ground-wheel.

To enable those skilled in the art to'fnl'ly understand and construct my invention, I will proceed'to describe it; a

A represents the platform of a reaper; and B is the main frame, to the back part of which F the sickle-bar O is attached.

In the back part of the mainframe B there is placeda vertical shaft, D, to the upper end of which an arm, 0,. is attached at right angles. The upper part of the shaft 1) has its hearing in a metalplate, F, which has a cam-shaped slot, Gr, made in it. The 'form ofthis slot'is, shown clearly in "Fig. 2, a being .a 'straightportion; b, a

curved portion and c, a short portion, curved about concentric with a portion'ot' b, (indicated between the points 1-1,) 1

To the upper surface of the niain frarneB, at its back end and inner side,there is attached by-a bolt, d, a oar,'H, ,whichis'slotted-longttudinally nearly its whole length, as shown at s e. e The bolt d passes through the bar near? one end, and said bolt is allowed to turn freely in the plate'F.-

lazy-tongs, the fixed'fuleruui of which is on the bolt'd. 'To one end of the lazy-tongs a rake, J, is attached, said-rake projecting down toward the platform A, and nearly touching the slot G of plate E. r v

The'arni E of theshaft I) is-directlyoverthe plate F,'and said arm is sufficiently longto' through the; slot 6 in the bar H,and through traverse over the wholeof the slot Gr as "the througlfan eye gyon the bolt d,

:To the, outer endof the. bar Ha" rake o'r ,gpressure-plate, M, isattachedby elastic rfods It,

so as to allow said plate to have a certain d'egreeof elasticity or yielding movement. Y To the upper parts of theeyes f g a frame, N, is attached. This frame may be fornied'of is attaehed,-saidwire or.rod being near the outer end of the platform. j The operation is as follows" As the harvester is drawn along. the shaft D is rotated from" the forces the pin K around the-slot G in plate operates the lazy-tongs and the, Mail, the lat- I ter being moved-from a' positionat-rightam Fig- 2,--t-he bar H being; vibrated; back and 'forthfrom'o'n'e of these positions-totheother. The lazy -ton gs are eipa-uded and contracted by the movement ofpin K expanded when the. .barHhas aL-transverse-v position on the main being contracted while the pin K moves in the straight .part-w-o'f slot G,*and causing the rake J ztofd'raw the cut grain on-the platform toward latter is in-o'peration.1 When jthe' rake J ,has :reached the endof its/stroke towardtheplate moves the 1 .31? 1H to? afpo'sition longitddiual gles or transverse .withjthe main frame to a. position longitudinal with it; as shown in red,

with the main frame, and eonsequently the Having this described myinyention, what I rake J and plate M, with theircontents, will be turned oif the back of the platform, as.

shown in red, Fig. 2, and as the pin K passes around the larger curved portion 1) of slot G 'the lazy-tongs will be expanded and the rake J moved off from the plate, so that the gavel will be ieleased and allowed to drop on the stubble behind the main frame. As the lazytongs are expanded, they are moved around over the platform A, toa position parallelwith the sickle, so as to again sweep over theplatform and gather the grain thereon between it and plate M. The spring-rod O elevates the end of the lazy-tongs as they pass over the back part of the platform, and compensates for any deflection of the lazy-tongs which might .occur from use and wear or a lack of requisite stifi'uess of itsparts.

claim as new, and desire to secure by Letters Patent, isr p 1. The employment or use of the lazy-tongs I, with rake J attached, in connection with the bar H, with the'rake or plate M attached, the

lazy-tongs and-bar being operated by the re-- volving arm E, pin K, and slot G, substantially as described.

2. The frame N, in combination, with the lazy-tongs I, for the purpose of preventing the grain that is being out, while the rake is. in op-' eration or passing over the platform, interfering withoperationof the rake, as specified. DANIEL GUBTAIL.
